Daniel P. Berrangé bb71d9fe14 hw/audio/via-ac97: skip automatic zero-init of large array ...

The 'out_cb' method has a 4k byte array used for copying data
between the audio backend and device. Skip the automatic zero-init
of this array to eliminate the performance overhead in the I/O hot
path.

The 'tmpbuf' array will be fully initialized when reading data from
device memory.
